Re: EXPECT script - escaping special char's

I have an expect script, that chokes on the env variable definition
below...

#!/usr/local/bin/expect -f
set timeout 20
spawn sftp -vvv -oport=22 jay@xxxxxxxxxxxxxxxx
expect {
default {exit 2}
"continue connecting (yes/no)?" {send "yes\n"; exp_continue}
"password:" {send "$env(SSH_PASS)\n"; exp_continue}
"sftp>"
}


it chokes on the red env variable above (most likely because of the $)...

can't read "env(SSH_PASS)": no such variable while executing "send
"$env(SSH_PASS)\n""



Does anyone know away to escape the $ in the script? I got this from
Scott Klement link, but it did not address the escaping of the $...
